新型高效低阻'纳米纤维嵌入式'复合滤料的制备

摘要

DMF was used as solvent to dissolve PAN powder and the resulting solution was employed to prepare PAN nanofibers with diameter of about 400 nm by using high-pressure electrospinning technology. And after needle-punching process, the "nanofiber-embedded" composite filter material was produced. Test results indicated that this novel composite filter has excellent filtering property, which has a huge potential to filter the ultramicron under 1~2 μm.%以DMF为溶剂溶解PAN粉末,采用高压静电纺丝技术制备直径约为400 nm的PAN纳米纤维,以独特的结构复合,经针刺制成新型"纳米纤维嵌入式"复合滤料.结果表明,"纳米纤维嵌入式"复合滤料具有优异的过滤性能,尤其对于 1 ~ 2 μm及以下的超微粒子具有极大的过滤潜能.
